2.Spatial regression analyses of the impact of spatial transformation of agriculture on habitat quality
Selection of a suitable spatial regression model to analyse the spatial coupling between multifunctional transformation of agricultural space and changes in habitat quality. By identifying the transformation of the dominant functional type of the image elemnt or selecting the change of the functional value as the explanatory variable (X), and the change value of the habitat quality of the image element as the explanatory variable (Y), to explore the influence law and weight coefficients. The more significant spatial regression model was selected for regression analysis by LM test and robust LM test.\

Expected results:\
The overall trend of multifunctional development of agricultural space is multi-functional, and the functional values of different dimensions are gradually becoming more balanced. Habitat quality will improve in areas with a high level of multifunctional development or a more balanced development of agricultural space; in areas with a medium level of multifunctional development and a rapid increase in the value of the subsistence function, ecosystem services will be degraded and habitat fragmentation will occur, and habitat quality will decline; and habitat quality will be more or less unchanged in some single-function-dominated areas.\
